Answer:
Step-by-step explanation: To find the area of a circle with a radius of 3 units, start with the formula for the area of a circle.
In this problem, we are given the radius of the circle which is 3 units so we can plug a 3 into our formula.
Remember that 3² is equal to 3 units x 3 units or 9 units².
The reason we square the units is for us to remember that we are dealing with area and not a 1 dimensional or 3 dimensional figure.
